Question:
Use the formulas below to find the surface area and volume of the cube, sphere, and cylinder “ice cubes”.
“Ice cube” measurements:
• Cube: s = 3 cm
• Sphere: r = 1 cm
• Cylinder: r = 2 cm and h= 3 cm
Note: After you find the surface area and volume of each shape, divide the surface area by the volume to find the surface area to volume ratio expressed as a single number. This should go in the last column.
Answer:
<em><u>Cube: </u></em>
Surface area =
Surface area = 6 (3)(3)
Surface area =
Volume =
Volume =
Volume =
Surface Area to Volume Ratio = =
= 2:1
<u><em>Sphere:</em></u>
Surface area =
Surface area =
Surface area =
Surface area = (rounding off )
Volume =
Volume =
Volume =
Volume = (rounding off )
Surface Area to Volume Ratio = = 13 : 1
<em><u>Cylinder:</u></em>
Surface Area
Surface Area =
Surface Area =
Surface Area =
Surface Area =
Surface Area =
Surface area = 63 (rounding off )
Volume =
Volume =
Volume =
Volume =
Volume = 37 .699
Volume = 38
Surface Area to Volume Ratio = = 68 : 38
